Guess Who Won the Ron Nyholm Award

Ron Nyholm was an Australian inorganic chemist. His work mainly focused on preparing transition metal compounds, particularly those with arsenic ligands. He also was a passionate supporter for the improvement of science education. He is best-known in chemistry classrooms for his precise measurements of bond angles in molecules and his predictions of the shapes that various molecules would assume based on each element’s valence — the configurations of the outer electron shells of elements. I learned about this aspect of … Continue reading

Mind-Reading may soon be a reality

By looking only at maps of electrical activity in the human brain, scientists were able to tell which words a person was listening to. The discovery is a major step toward being able to “hear” the thoughts of people who can’t speak. “If someone was completely paralyzed, or if a patient had locked-in syndrome with no movement, but the brain was still active and we could understand it well enough, we could develop devices to take advantage of that and … Continue reading

The Fascinating History of the Chandrasekhar Limit

Young Chandra

Thanks to Phil Krause for suggesting this interesting subject – Deskarati – When a star starts running out of fuel, it usually cools off and collapses into one of three compact forms, depending on its total mass, a White Dwarf a Neutron Star or a Black Hole. The Chandrasekhar limit is the maximum mass of a stable white dwarf star. It was named after Subrahmanyan Chandrasekhar, the Indian astrophysicist who predicted it in 1930 at the age of twenty. After the earlier work of R.H Fowler and E.C. Stoner … Continue reading
